in different courts, and as such, their action before the ECOWAS Court of Justice does not amount to abuse of court process or estoppel res judicata. The Court therefore considers that its duty is to examine whether the two suits have the same subject-matter. It is apparent, in that regard, that if the facts in issue remain incontrovertibly the same, the substance of the actions filed before court greatly differ. The Plaintiff's action before the judge in the domestic courts of Nigeria was to seek criminal investigation and prosecution of the alleged killers and compensation for the loss of their breadwinners, whereas the object of matter before the ECOWAS Community Court of Justice is to ask the Court to find that there is an occurrence of human rights violation, and to seek reparation for the harm done, if the Court should so find. The texts relied on in pleading the two cases are equally different.· Before the national courts of Nigeria, the request sought application of the provisions of the domestic criminal law of Nigeria, whereas before the ECOWAS Court, the request was to urge the Court to find an occurrence of the alleged human rights violation, essentially derived from the African Charter on Human and Peoples' Rights, which Nigeria is party to. The two proceedings thus instituted are therefore independent of each other; they do not overlap, and one cannot be confused for the other. Similarly, the Court is of the view that in entertaining the instant case, the Community Court of Justice, ECOWAS is not acting as an appellate court, since the case filed before it does not have the same substance as the suit filed before the judge in the domestic court of Nigeria. The concept of "appeal" presupposes that the same case is transferred to a higher court, so as to adjudicate on the same facts and to examine the same arguments of the parties; but such is not the case here. The Court thus holds that the thesis that the two suits are totally identical, cannot be upheld; and hence, the Court holds that the Plaintiff's right to bring their case before the ECOWAS Court of Justice cannot be contested. For that reason, the Court rules that the preliminary objection thus raised by the Federal Republic of Nigeria is ill-founded, and the Court receives the action brought by the Plaintiff as admissible.
